IPXFWSTOPSIG(3F) Last changed: 1-6-98
NAME
IPXFWSTOPSIG - Returns part of the lower bits of signal number that
terminates child process
SYNOPSIS
INTEGER FUNCTION IPXFWSTOPSIG(istat)
INTEGER istat
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
DESCRIPTION
The IPXFWSTOPSIG integer function returns part of the lower bits of
the signal number that caused the child process to stop. The
PXFWIFSTOPPED logical function returns TRUE to indicate that the child
process has stopped. IPXFWSTOPSIG should only be used if
PXFWIFSTOPPED returns TRUE.
The following argument is used for this routine:
istat An input integer variable with the PXFWAIT or PXFWAITPID
output status argument.
On IRIX systems, this routine is in libfortran.so which is linked by
default when compiling programs with the MIPSpro 7 Fortran 90 compiler
or when compiling programs with the -craylibs option to the MIPSpro
7.2 F77 compiler.
When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
kind unless documented otherwise. On UNICOS and UNICOS/mk, default
kind is KIND=8 for integer, real, complex, and logical arguments; on
IRIX systems, the default kind is KIND=4.
